To all whom it may. concern:

Be it known that 1, JOHN HoHENADEL, a citizen of the United States ofAmerica, residing in the city and countyof Philadel .phia, in the Stateof Pennsylvania, have invented a certain new and useful Im rovement inRoller-Skates,of which the ollowing is a true and exact description,reference being had to the accompanying drawings, which form a partthereof.

My present invention relates-to roller skates and" has for itsiobj'ectthe provision of roller .skates with-braking devices applied to theskates in such'a'ma'nner as not to interfere with their ordinary use,while at the same 'timethe braking I devices may readily be brought into[operation whenever necessary or desirable] H A further object of myinventionis the provision on a rollerskate of abraking device which inaddition toits braking func tion may also serve as a maneuvering device,assisting the skaterin controlling the char acter of themovementsexecuted by him- In carrying out my invention, I mount on theskate body, in addition to the ordinary rollers, an extra rollerjournaled on ashaft. extending in a substantially transverse dimotion tothe axis of the rotation. of the ordinary rollers. Preferably I locatethe extra roller beneathorclosely adjacent the toe end of the skate bodywith its sup orting shaft extending parallel to the genera direction ofthe skate body and so that the extra roller clears the floor by asubstantial amount when all of the ordinary rollers bear on the floor,but so that the extra roller may be brought into contact with the floorwhen the skate is tilted so that all its ordinary rollers, or at leastthe rear rollers, are above the floor.

The various features of novelty which characterize my invention arepointed: out with particularity in the claims annexed to and forming a.part of this specification. For a better understanding of my invention,however, reference may be .had to the accompanying drawings and descritive matter in which I have illustrated an 1 described one of the formsin which my invention may be embodied.

Of the drawings, Figure 1 is a side elevation of a roller skate havingmy invention applied to it. Fig. 2 is an inverted plan view of the skateshownin Fig. 1. 'Fig. 3 is a front elevation of the skate shown in Fig.

1 andFig. 4 is a sectional elevation of the extra roller taken on theline 44 of Fig. 2.

In the'form of my invention shown in the drawings, Arepresents the skatebody which maybe of'any usual form and is provided with the usual frontrollers B and rear rollers C and withsuitable devices for securing theskate in place such as the hook D and clamp E. i

. Against the under surface of the toe end of the skatebody A is secureda bracket F as by rivets F passingthrough flange portions F 2 of thebracket. bracket extends downwardly and supports at its lower end a studor shaft G which forms a'bearing for the extra roller H. A brace Farranged as shown, serves to stiffen the body of the bracket. Preferablythe extra roller H is substantially spherical as.

shown and has its outer portion formed of resilientand yieldingmaterial. shown, the body of the roller H is formed of rubber and has init a bushing or sleeve H of suitable material, as metal or wood, whichsurrounds the shaft G. The roller H is supported at its rear by a washerH bearing against a boss or shoulder F surrounding the shaft Gandspacing the roll away from the body of the bracket F. The front end ofthe bushing H is enlarged at H and. is received in a recess Hhformed inthe roller H. The roll is secured in. place in any suitable manner, asby an enlargement of the outer end of the shaft G formed by a shortheaded bolt I tap ed into the end of the shaft G, the head of t e boltbearing against the enlarged end of the bushing H and being entirely re-As shown, the body of the In the form .ceived in the recess H formed inthe outer 4 .of'the 'extra roller and hence the bolt cannot be broughtinto engagement with the floor.

With skates of the character just described the skater may arrest themovement of either. foot at will by simply tilting the skate until therollH engages the floor with the desired pressure and this withoutnecessarily lifting allweight off the front pair of rollers. The extraroller may be brought into play as a maneuvering device when executingcertain movements not otherwise readily possible by moving the skatelaterally while the extra roller bears on the floor. The character ofthe movement thus produced can, of course, be varied largely by varyingthe proportion of the weights put upon the front rollers and the extraroller and the position and amount of movement given to the skate body.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is,

1. In a roller skate, the combination with the skate body and the usualsupporting rollers, of another roller pivotally supported by the skatebody at the toe end of the latter to turn about an axis extending in adirection generally transverse to the axis of rotation of saidsupporting rollers, said other roller being so located that it isnormally above the floor, but may be brought into engagement therewithat the will of the skater.

2. In a roller skate, the combination with the skate body and the usualsupporting rollers, of a roller closely adjacent to the toe end of theskate body and a supporting shaft for the roller which extendssubstantially arallel to the general direction of the skate body and isso located relatively to the skate body and the usual rollers that theroller supported on it is normally held above the floor level, but maybe brought into engagement therewith.

3. In a roller skate, the combination with the skate body and the usualsupporting rollers, of a bracket secured to the skate body at its toeend, and a substantially spherical roller pivotally supported by saidbracket to turn relatively thereto about an axis extending substantiallyparallel to the general direction of the skate body.

4. In a roller skate, the combination with the skate body and the usualsupporting rollers, of a bracket secured to the skate body at its toeend, and a substantially spherical rollerpivotally supported by saidbracket to turn relatively thereto about an axis extend.- ingsubstantially parallel to the general direction of the skate body, theouter portion of said spherical roller being formed of resilientmaterial.

5. In a roller skate, the combination with the skate body A and theusual supporting rollers B and C, of the bracket F secured to the skatebody A at its toe end the shaft G- carried by the bracket F andextending substantially parallel to the general direction of the skatebody and having the enlarged outer end and the roller II of resilientmaterial journaled on the shaft and having the recess P H receiving theenlarged outer end of the shaft.
